Application January 30, isaaiseriamonams iolaim. ':(Cl. 292-43363) meant an assembly in which the means for actu- .ating ;a lock bolt lie substantially between *the planes ,de'fin'ingthe outer and'inner faces of the closure. Preferably, the means serving as the actuating handle are .disposed'flush with Ithe .ad-

jacent ,outer face of th closure, Such ,type :of

"closure handle and lock is of "particular "advan- .tage when used 'on utilityinstallation and'mainitenance vehicles operating fin :rough terrain wherein outwardly 'la'terally-aextended closure handles are subject 'to being severely damaged or torn oiT from the-vehicle.

The invention is herein illustrated by a. showing in the accompanying drawings and a description of an application thereof to a utility vehicle door.

The instant improvements in flush panel construction door handles and locks can be utilized on both horizontal and vertical doors, and also on double paneled or single paneled metal doors.

The claims of the present application are limited to the improvements in a closure locking bolt operating structure.

The annexed drawings and the following description present in detail certain means illustrating our improvements in closure handles and locks, the same describing and showing, however, only one form of assembly in which the invention may be embodied.

In said annexed drawings:

Figure 1 is an exterior elevation of a door for an opening or a compartment of a utility vehicle in which our improvements in closed handles and locks are incorporated, a fragmentary portion of the surrounding vehicle body on which the door is hinged being also shown;

Figure 2 is a fragmentary exterior elevation, upon an enlarged scale, of a vehicle door and a body on which the door is mounted, with the improved door handle and lock assembled therein, a portion of the door being broken away;

Figure 3 is a vertical transverse section, taken in the plane indicated by the line 3.3, Figure2;

Figure 4 is a longitudinal horizontal section, taken in the plane indicated by the line 4-4, Figure 2; and

Figure 5 is a longitudinal horizontal section, taken in the planes indicated by the line 5-5, Figure 2.

Referring to the annexed drawings in which the same parts are indicated by the same several 2 numbers in the respective -views, a *Tragmentary portion of a vehicle body'is'indicatedby l, the same having "a'latch recess-2 whose wall is engaged'bya door-lock bolt 3. The body I has an opening or a wall compartment for which a hinged closure such *as the door is provided.

The door 4, in "the design of'door shown 'for pur- ,poses of illustration in'the 'accompanyingdrawings, is a'box-like body "'5 and "has an exterior interiorly projected peripherally flanged dish-like or cup member 1 whose flange 8 exterior-1y laps the outside face of the outer doorb'o dy wall 5 "and whose 'baseabuts the inner door body wall-i In the .form .of the invention shown in the accompanying drawings, the cup member "l is a plate "of dish-like cross section, and "serves as a liner for 'the'recess 4 which Ebreaks the exterior surfaceof the closure I.

Rigidly secured adjacent one side *to a rod H! by relatively right angular inwardly extending elongated end flanges 9 is a panel 9 whose outside face is aligned with the outside face of the flange 8 so as to form a substantially plane door surface with the outer door wall 5 The panel 9 extends from adjacent its secured side at one side of the flange 8 a substantial distance toward the opposite side of the flange 8 providing an opening beyond the panel 9 into the interior of the cup 1 between a swinging edge 9 of the panel 9 and said opposite side of the flange 8, as clearly appears in Figure 1. The rod l0 passes through the closure recess 4 bounded by the cup member I and is pivotally mounted adjacent its ends in the intermediate wall member I of the cup member 1, one end portion ll of the rod being projected somewhat beyond the side member I and mounted in an elongated bearing block l2 welded to the side wall 1 the end portion of the rod Hl extended beyond the bearing block i2 being secured to and adjacent one end of a member 13 having an opposite end lock-bolt retracting portion 14 acting as a cam as hereinafter fully described.

Adjacently within the side wall I of the dishlike liner 1 the rod I0 is mounted in opposed bearings 25 which are in contact with the inner face of the side wall 1 In addition to serving as bearings the members 25 serve a double purpose. In the first place, they act as spacers whereby the panel 9 when being actuated will. not rub on the liner 1. Secondly, the bearings 25 catch any water driven into the recess 4 and deiiect it and thus obviate its obtaining access to the door compartment.

Secured by a flange H to the interior wall 5 of the door 4 by screws l6 and enclosing the body of the lock-bolt 3 is an open-ended housing I! through one open end of which extends the end of the bolt 3 which engages the vehicle body recess 2. Positioned intermediate the flange I'l of the housing I! and the inside face of the inner door wall is a wearing plate I8 upon which the lock bolt 3 slides during its opening and closing movements. The lock bolt 3 is formed with a recess l9 into which the lock retracting portion [4 of the member I3 extends and in which it can play and engage an adjacent wall of the recess [9 to retract the bolt from its door holding position in the recess 2 so as to permit the door 4 to be opened. The lock bolt 3 is normally held in latching position by a compression spring 20 positioned in a second recess 2| formed in the lock bolt 3 and having as one wall an abutment 22 formed by a portion of the wearing plate I8 which is struck up so as to extend inwardly of the wearing plate into the recess 2|, as clearly appears in Figures 2 and 5.

It is apparent from the foregoing description, upon reference to the accompanying drawings, that the panel member 9 can be manually grasped at its edge 9 and pulled outwardly and the panel member 9 with the rod H] to which it is secured turned on the axis of the rod so as to turn the member l3 and cause the cam portion l4 thereof to retract the bolt 3 against the compression of the spring 20.

A key-operated lock 23 for the door 4 to prevent the opening thereof by actuation of the panel member 9 is shown in Figures 2 and 5, there being secured to the rotatable barrel of the lock 23 one end of an elongated plate 24 having an angular end abutment 24 which can be turned by the door key into a stop position adjacent the inner end of the lock bolt 3.

What we claim is:

A locking-bolt operating structure, for a closure having a recess breaking its surface, comprising a dished plate for the recess having a marginal portion abutting the outer face of the closure, opposed bearings in contact with the inner face of the side wall of the plate, a rod pivotally mounted in the bearings and intersecting the plate side wall for turning movement therein, bolt-actuating means, an elongated bearing secured to the exterior face of the plate side wall, the rod being extended through said elongated bearing and secured at one end to the bolt-actuating means for operation of the latter on turning movement of the rod, and a panel covering the rod and having its exterior face substantially flush with the marginal portion of the plate, the panel having flanges secured to the rod to turn the latter.
